A framework for distributed access control in multimedia wireless cdma networks

Abstract EN

This paper addresses some challenges that face multimedia CDMA wireless networks.

We highlight problems related to power assignment, admission control, and other radio resource management functions.

At the core of our approach is a novel definition of an index for Quality of Service (QoS).

The proposed QoS vector can easily be defined on a network wide basis and be negotiated during the call set up.

Furthermore, we show that it is possible for a radio resource manager to assess the radio resource requirements of the new connection based on the proposed QoS vector and to participate effectively in the end to end call set up negotiation.

The paper also introduces a simple but effective method for access control to CDMA networks and a linear power assignment scheme to complement the proposed admission control strategy.
